System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle, or stationary object ahead
of you, for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potential traffic such as a rider
on horseback. The system may also not detect
smaller moving objects such as motorcycles or
bicycles. Be especially alert when encountering
any of these situations as the system will nei-
ther automatically brake, nor provide a warning
to you. Also, be aware that every decrease in
the distance setting allows your vehicle to come
closer to a vehicle in front of you and requires a
heightened amount of alertness. <
Active Cruise Control is not and must not
be used as a collision avoidance/warning
system. <
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactiva te the system when
you pull into an exit lane for a highway off-
ramp. < Also, vehicles travelin
g in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
While Active Cruise Control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the
system to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when
a much slower vehicle cuts in front of you at
close range. <
Active Cruise Control ca n only decelerate the
vehicle to approx. 20 mph or 30 km/h.

ControlsDriving
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, Active Cruise Control will not
recognize this vehicle until it is fully in your lane
ahead of your vehicle.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to maintain the selected distance automatically.
This also applies to gr eat differences in speed
between you and vehicles ahead, e.g. when
quickly approaching a truc k. There is a risk of
collision. Once the system has established that
a vehicle is indeed in fron t of you, it will indicate
that you must brake and/or maneuver the vehi-
cle yourself. Take action yourself; otherwise,
there is a risk of an accident. <
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a sp eed that is prudent in
view of the curves and terrain of the roadway. In approaching a curve, it is possible that Active
Cruise Control wo
uld react briefly to a vehicle in
the adjacent lane. In a ddition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Your responsibility
Your actions have priority at all times. When you
press the accelerator pedal while driving with
Active Cruise Control, the automatic braking
function will be temporar ily interrupted. Once
you release the accelera tor pedal, the desired
speed or the selected distance to the vehicle
ahead is achieved again.
Do not leave your foot on the accelerator
pedal and make sure that no objects such
as floor mats are lying on the accelerator pedal.
Otherwise, the system may not be able to brake
the vehicle.<

Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi
cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.

Setting the time, refer to page 90.
Outside temperature warning
When the displayed temperature sinks to
approx. +377/+3 6, a signal sounds and a
warning lamp lights up. There is an increased
risk of black ice.
Black ice can also form at temperatures
above +37 7/+3 6. You should there-
fore drive carefully on bridges and shaded
roads, for example; otherwise, there is an
increased risk of an accident. <
Odometer and trip odometer
Resetting the trip odometer:
With the ignition switched on, press button 1 in
the instrument cluster.

Tachometer
Never force the engine speed up into the red
warning field, see arrow. In this range, the fuel
supply is interrupted to protect the engine.
Engine oil temperature
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/100 6 and approx. 300 7/
150 6.
If the engine oil temp erature is too high, a
message appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 16.1 US gal/
61 liters.
You can find information on refueling on
page 233.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level ha s fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message rema ins in the Control
Display.
With a dynamic driving style, e.g. rapid corner-
ing, engine functions are not always assured.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur. <
